How coworkers impact the value of your skills

A recent study by Harvard's Growth Lab analyzed administrative data on Sweden's 9 million inhabitants, finding that workers with complementary coworkers earn high wages and returns on education, comparable to having a college degree. The research offers a tool to assess the right and wrong coworkers in fields of expertise.

There is no 'I' in team -- or is there?

A study published in the Journal of Occupational and Organizational Psychology found that individual psychological ownership boosts personal engagement and creativity, but decreases collective effort. Conversely, collective ownership enhances team engagement, but not necessarily individual performance.

Smaller class sizes not always better for pupils, multinational study shows

A multinational study of 4,277 pupils from 151 schools found that smaller class sizes were only associated with improved non-cognitive skills in Lithuania. In Romania, however, smaller classes led to greater academic achievement and enjoyment of learning mathematics and science. The study's results suggest that reducing class size does...

Birds are shrinking as the climate warms

Over 40 years of data show that migratory birds have been getting smaller as the climate warms. The birds' body masses, leg bone lengths, and overall body sizes all decreased, while their wingspans increased, likely linked to rising temperatures.

Oil and gas well leakage in British Columbia

Researchers analyzed data on oil and gas well leakage in British Columbia, finding that 10.8% of wells showed reported leakage, with most incidents involving gas venting. Unremediated surface gas leakage from abandoned wells is estimated to produce significant GHG emissions, equivalent to nearly 75,000 metric tonnes of CO2 per year.

Benefits of exercise referral schemes not as large as hoped

Exercise referral schemes have been shown to improve physical activity levels among individuals with long-term conditions. However, the analysis of data from 23,731 participants found that while significant improvements were observed in most measures, they did not reach clinical thresholds for meaningful impact.

Changing weight-loss strategies, attempts

The proportion of adults who tried to lose weight increased from 1999 to 2016. Despite this surge, observational study findings suggest the results may not be reliable due to limitations in self-reported data. Commonly reported weight-loss strategies included eating less food, exercising, and drinking more water.

Your dog might be hiding its true colors

A study from Purdue University found that some breeds of dogs have hidden coat colors and other traits due to genetic variations. The researchers analyzed data from 212 dog breeds and discovered that up to 48 breeds possess the tailless gene variant, often at low frequencies.

Political affiliation may help drive and shape a person's morals

A new study found that people's moral foundations are better predicted by their political attitudes than vice versa. The researchers tracked participants' moral values and political leanings over time, revealing that those with stable political beliefs were more likely to have consistent moral foundations.

Rare diseases: Over 300 million patients affected worldwide

A recent study by Inserm US14 found that more than 300 million people worldwide are currently living with a rare disease, which represents around 4% of the world's population. The study analyzed data from the Orphanet database and estimated that this number could be higher due to many cases being unrecorded in healthcare systems.

Earthquakes in slow motion

Researchers have characterized slow-slip events more precisely than previously possible, finding they obey the same scaling laws as regular earthquakes. This discovery opens the door for geoscientists to study these frequent and nondestructive events to better understand earthquake mechanics.

Citation networks across disciplines

A study analyzing research article data from 1950 to 2018 found that the average distance between articles on citation networks decreased over time, while ties between articles from different fields increased. Citation networks depend on high-impact articles, suggesting increased interconnectivity among scientific disciplines.
